There is more to a motor than just the wind (number of turns).
All things equal a handwound motor will still be faster than a machine wound. Maybe not a whole lot but still faster.
The armature will have less wire on it (less resistance = more power) and be a bit more effecient.
If you buy an Outlaw the wire used will be thicker than the wire used on a Chameleon/atlas or other spec motor.
Thicker wire = less resistence = more power.
The groove in the center of the arm will also make a bit more HP than and arm without it.
The difference between a spec motor and a 19T "mod" is quite eurhm, huge
IMO DC motorsports makes the best 19T but Br00d has a very nice one as well.
